Can Blender easily render a single image from 3D source files?
The types of images you mention are what you would use in blender to control the surface appearance of a 3D object, that you then position and render into a 2D image.

If you want to merge multiple images into one image, you would be better off using a 2D image editing program like GIMP or Krita. Another option could be using ImageMagick to combine them using the CLI.
